That Dragon, Cancer documentary follows a year of development, heartache

Thank You For Playing is a documentary about the development of That Dragon, Cancer, the low-poly adventure game from Ryan Green. The game tells the Green family's heart-wrenching story as their young son, Joel, battles terminal cancer. Joel died in March at age 5.

The documentary covers the past year of development, delving into tense family moments, following Joel to the hospital, and covering That Dragon, Cancer at shows such as PAX and E3. Thank You For Playing comes from veteran filmmakers David Osit and Malika Zouhali-Worrall.

Ryan Green posted about the documentary for the first time on his blog today:

"You wouldn't think it so, since our family has been so public and in the news about sharing the game, and we've been part of a web-based documentary before, but letting a film crew in to our personal, creative and professional lives was a little scary. We are not the producers of this film. It is independent of us. Before this project, we did not know David and Malika, but we decided It was important that people see the parts of our lives in-between the scenes of the game. Life happens in the middle and so does death. David and Malika were with our family the three days leading up to Joel's passing."

Thank You For Playing is currently in production, as is That Dragon, Cancer.
